Great Service




Phil did a wonderful job! He initially came to give us estimates but ended up fixing a serious water heater issue on the spot. He clearly explained everything to me and made sure I was educated about each issue.

Ryan and Black Diamond are the best!




Ryan took the time to answer all my questions, and explained all options for new air conditioning units. He’s very knowledgeable, professional, and courteous. I’ve used Black Diamond for various services over the years and they always do amazing work at reasonable prices. Black Diamond gets my highest recommendation.

Awesome service!




Doug from Black Diamond was out within half an hour of me calling. He saved the day with my desperate need to get a socket wired for a brand new microwave and replaced the wall socket for the stove as well. I love black diamond and will definitely use them again. Doug was awesome!!

Sump pumps




Dan Corcora tested each of the 4 sump pumps pus one back-up. He checked that each pit was maintained by the Generac House Generator. We chose to replace three of the pumps. We also discussed replacing several shower heads. Briefly, Dan was a breath of fresh air. Incredible

Great Service, Knowledgeable Employees




We had a horrible smell coming from our water that we tried to get rid of for months and we called several plumbers. None seemed to know what we were talking about. I called Black Diamond and Josh Panos came out the same day and fixed our problem in just a couple hours. I am really pleased with our experience and I will definitely recommend Black Diamond to anyone looking for a plumber.


Prompt service. Great workman! Great customer service!




As always a pleasant experience working with Black Diamond.


Electrical Work




Jared was great, on time, professional and thorough. Please share my gratitude with him as was very helpful. I will be sure to recommend him to the neighborhood.


Great




Unfortunately I was not home when Matt came. I had to work so my son came over to let them in. When I got home I saw the work that they had done. The fan was installed beautifully and works fine. Looks like they did a great job. No fuss, no mess. I will continue to use Black Diamond due to the quality and efficiency of their work and their overall professionalism.


repair leak/faucet installation




Josh did an excellent job. He was professional and courteous.


Great experience




We've been ripped off by plumbers before and this was a breath of fresh air. The guy was super informative and friendly. Thought the price was a bit high but for the quality, convenience, and information I'll take it. Definitely calling back for work later this year! Work was done quickly and he gave us preventive tips.


Rick does a great job.




Black Diamond is very professional and efficient. They get the job done.


Outstanding




I called black diamond to get an experts guidance. I got what I was looking for.


Good Job under poor conditions





Quick




Service guys were very polite, walked me through every step of air conditioner instillation, and were lightening fast. I was originally told by sales that it would take better part of the day but they were done in 3.5 hours!!! I was able to go on with the rest of my day!


Perfect service
